Biofeedback: Understanding And Controlling Physiological Functions.

Understanding Biofeedback

Biofeedback is an intriguing and increasingly popular form of alternative therapy.

Definition of Biofeedback

Biofeedback is a technique designed to enable an individual to learn how to change physiological activity for the purposes of improving health and performance. It provides you with real-time information about your body’s functions, such as heart rate or brainwaves, thereby allowing you to gain greater awareness and conscious control over them.

History and Development of Biofeedback

Though biofeedback as a formal therapeutic method has only been recognized for a few decades, the roots of this practice extend back to the ancient yogic tradition of mind-body control. The modern incarnation of biofeedback was born out of research conducted in the 1960s and ’70s, where the potential for self-regulation of the body’s functions using electronic devices was first acknowledged.

Principles Behind Biofeedback

Biofeedback operates on the premise that we are often unaware of many of the body’s functions, which are regulated by our autonomic nervous system. By using sensors and electronic devices to monitor these functions, biofeedback makes you actively aware of these processes. This awareness is then used to teach self-regulation, allowing you to exert conscious control over what are usually automatic bodily processes.

Types of Biofeedback

Several types of biofeedback exist, including Neurofeedback (brainwaves), Heart Rate Variability Biofeedback, Electromyography (muscle tension), Thermal Biofeedback (skin temperature), and Galvanic Skin Response Training (perspiration). Each targets a specific physiological function that you can learn to control.

Biofeedback Methodology

Biofeedback Instruments and Devices

Various devices and instruments are used in biofeedback to provide data on different physiological functions. These might include electrodes and sensors attached to your skin, or straps placed around your chest or abdomen. These devices are connected to a computer that displays your body’s responses, providing you with live feedback.

Biofeedback Sessions: What to Expect

Usually, a biofeedback session involves you being connected to one or more devices to monitor your physiological processes. A therapist will guide you through relaxation or concentration exercises and will help you interpret the signals from the devices. Eventually, you’ll learn how to control these processes on your own.

Role of the Biofeedback Therapist

The biofeedback therapist is pivotal for directing and interpreting the biofeedback session. They guide you by explaining the process, leading exercises or techniques during the session, and helping you understand the information being provided by the biofeedback devices.

Home-based Biofeedback

Some devices for biofeedback can be used at home, allowing you to receive the benefits of biofeedback without regularly visiting a clinic. The effectiveness of home-based biofeedback depends on your dedication to learning and practicing the techniques.

Physiological Functions Controlled by Biofeedback

Brainwave Activity

Brainwave biofeedback, or neurofeedback, monitors the brain’s electrical activity. It can enhance relaxation, focus, and mental agility, and help manage conditions like ADHD, anxiety, and depression.

Heart Rate

Heart rate variability biofeedback teaches you to control your heart rate, which can help manage stress, anxiety, and some cardiac conditions.


By regulating your respiratory rate and rhythm, you can achieve a state of relaxation, manage stress, and relieve symptoms of conditions like asthma.

Muscle Activity

Electromyography (EMG) biofeedback provides information on muscle tension, helping you learn how to relax your muscles at will—a useful technique for managing conditions like chronic pain and migraines.

Body Temperature

Thermal biofeedback utilizes sensors to monitor skin temperature, teaching you to increase blood flow to extremities, aiding in relaxation and stress reduction.

Sweat Gland Activity

Galvanic skin response training measures sweat gland activity, which often increases during stress or anxiety.

Benefits of Biofeedback

Managing Stress and Anxiety

Biofeedback can help you learn relaxation exercises and techniques that promote a calm, relaxed state of mind, which can be pivotal in managing stress and anxiety.

Pain Management

By providing you with the ability to control muscle tension and blood flow, biofeedback can play a vital role in managing chronic pain conditions, headaches, and migraines.

Improving Sleep Quality

Through relaxation and stress management techniques, biofeedback can help combat insomnia and improve overall sleep quality.

Enhancing Concentration and Focus

Particularly, neurofeedback can help you gain greater control over your mental state, potentially enhancing your ability to concentrate and focus.

Maintaining Emotional Balance

By helping you better manage stress and anxiety, biofeedback promotes emotional balance and well-being.

Biofeedback and Mental Health

Biofeedback for Anxiety and Depression

Biofeedback is shown to be effective in managing symptoms of anxiety and depression by promoting relaxation, enhancing emotional balance, and teaching stress management techniques.

ADHD and Biofeedback

Neurofeedback is particularly beneficial for people with ADHD, as it helps increase concentration, reduce impulsivity, and regulate hyperactivity.

Biofeedback for PTSD

Research suggests that biofeedback can help manage Post-Traumatic Stress Disorder (PTSD) symptoms by teaching individuals to regulate physiological responses to stress and anxiety.

Biofeedback in addiction recovery

As a part of a comprehensive treatment plan, biofeedback can support addiction recovery by helping individuals manage the stress and emotional turbulence that often accompany withdrawal and recovery.

Biofeedback for Physical Conditions

Biofeedback for Chronic Pain

By teaching individuals to consciously relax their muscles and regulate their own bodily processes, biofeedback can be an effective tool in managing chronic pain conditions.

Biofeedback and Cardiovascular Health

Heart rate variability biofeedback can improve cardiovascular health by teaching you to regulate your heart rate and stress response.

Biofeedback for Musculoskeletal Disorders

Biofeedback can aid in the management of musculoskeletal disorders like back pain or tension headaches by providing real-time information on muscle tension and teaching relaxation techniques.
